ROTARY MOTOR.

SPECIFICATION forming part of Letters Patent No. 518,145, dated April10, 1 894. g

Application filed August 9, 1893.

To all whom it may concern.-

Be it known that I, GUSTAV I-IEINICKE, manufacturer, a subject of theKing of Prussia, German Emperor, residing at Berlin, in the ProvinceofBrandenburg, Kingdom of Prussia, German Empire, have invented new anduseful Improvements in Rotary Motors, of

which the following is a specification.

My invention relates to rotary steam-engines, in which the piston hasthe shape of a ringsector, and moves around within a ringlike space of adisk-like cylinder, through the center of which the engineor main-shaft,driven from said piston, is passed; and my improvements in such rotarysteam-engines relate to the mode of connection between piston and shaft,or, in other words, to the mode motion of the piston to on a largerscale; Fig. 4 a vertioallongitudinal section through the cylinder, takenon line 8-9 of Fig. 3, and being also drawn on the larger scale; andFig. 5 is a horizontal section through the reversing-cock, drawn on ascale still larger than that of Figs. 3 and 4.

The cylinder consists of the two like parts a a, each of which has anannular groove a Both parts are firmly connected with each other by thebolts 5, and the whole cylinder is supported by the standards 0. Boththe grooves 00 together form the ring-like way in which the piston 61moves around. The opposite inner faces of the parts a a of the cylinderfit tightly upon another only beyond the grooves, but leave a flat spacebetween themselves at the part around the center, as is best to be seenin Fig. 3. This space affords the possibility of connecting the piston dwith the shaft e, which is accomplished in the following manner: Toshaft 2 is firmly secured the disk f, which, at its rim, is providedwith the teeth f, Fig. 4:. This disk is surrounded by a disk-like ringg, which, at

let can take place.

than has been attainable in such motors heretofore, especially when, incase of unequal warming of the parts in question, distortions of saidparts should occur. I

For the rest, the construction and manner of working of the motor is asfollows: The cylinder at a carries transversely on its headpart a casingit, within which rotates the disk '0' with its out 'i. Said disk isfixed to ashaft k, which is rotated from main-shaft e by thebevel-wheels Z Z and the chain-wheels m m. Shaft e carries also afly-wheel n, a pulley 0 and an eccentric p, the latter acting on theslide-valve within the valve-chest q, Figs. 1 and 2. The steam enters atr and flows through the channels 8', s and s of the reversing-cock s,Fig. 5, and through the inlet t, Fig. 4, intothe cylinder, thus drivingthe piston d in the directionindicated by the arrow. The outlet t hasits place on the other side of disk '5, and the position of the latteris such, thatno communication between inlet and out- Thus, the consumedand expanded steam in front of the piston escapes freely through outlett, and further through the channels 8 and s of cook 3. During therevolution of the piston, the diski is rotated, and, as soon as thepiston arrives in front of the disk, the position of the latter is such,that out 'i is in the under part of easing h, so that the piston mayfreely proceed in its motion. Inlet 15 had been closed already before,according to the required degree of expansion, and is opened again, whenthe piston has passed it, and (llSki has been rotated sufficientlyfarther to remove out 2' from the piston-passage a In order to reversethe engine, cock 8 (which is shown perfectly closed in Fig. 5) is turnedby forty-five degrees, by means of its handle u, so as to connect thechannels 5, and s and the channels .9 and .9, through which latter (3")the steam finally escapes.

What I do claim as myinvention, and desire to secure by Letters Patent,is-

1. In a rotary motor with annular pistonpassage, the combination withthe piston 01 revolving within passage 03, and with disk f fixed toshaft e, of an intermediate disk g, driven by the piston and adapted totransmit the motion of the latter to disk f, for the purpose asdescribed.

2. In a rotary motor with annular pistonpassage, the combination withthe piston d revolving within passage a and with serrated disk f fixedto shaft 6, of a serrated intermediate disk g, driven by the piston andadapted to transmit the motion of the latter to shaft e, the serrationsof both disks catchin g into another, for the purpose as described.

3. In a rotary motor with annular pistonpassage, the combination withthe piston 61 revolving within passage 0?, and with disk f fixed toshaft e, of an intermediate serrated disk 9 loosely connected with, anddriven by, the piston, and adapted to transmit the motion of the latterto shaft 2, the serrations of both disks catching looselyinto another,for the purpose as described.

In testimony whereof I have signed this specification in the presence oftwo subscribing Witnesses.
